Decomposition of Formic Acid and Acetic Acid into Hydrogen Using Graphitic Carbon Nitride Supported Single Metal Catalyst

In a combination of generation and storage hydrogen gas, both formic acid (FA) acetic (AA) have been notified as efficient carriers. This study was conducted to synthesize the monometallic catalysts namely palladium (Pd), copper (Cu), zinc (Zn) on graphitic-carbon nitride (g-C3N4) potential these in FA mixed (FA)-acetic decomposition reaction. Several parameters studied this work such type active metals, temperature, metal loadings. The mass percentage Pd, Cu, Zn used experiment are 1, 3, 5 wt%, respectively. At low temperature 30 °C, wt% Pd/g-C3N4 catalyst yielded higher volume gas with 3.3 mL, instead other Pd However, at 70 °C 98% concentration, 1 3 loading over g-C3N4 has successfully produced optimum (H2 CO2) 4.3 7.4 4.5 mL each reaction, showed high catalytic performance most element system ambient condition. Meanwhile, metal, reaction also increased thus producing more gas. it can be seen agglomeration particles formed loadings (5 wt%), remarkably lowering activity while °C. result for Cu catalyst, due small formation but presence oxide (CuO) (ZnO) promotes passive layer surface.
